How is intelligence separate from knowledge? Well, intelligence is learning and problem solving skills, while knowledge is information used in problem solving. Wisdom is a specific kind of knowledge in deciding the best course of actions.
So wisdom is a subset of knowledge, and intelligence is required for knowledge, and knowledge is indicative of intelligence.
Lumping these things together is thus in general accurate as they all correlate with each other (not to mention one is simply a subset of the other in terms of knowledge-wisdom).
Old age certainly does not mean you have more intelligence, that being mostly genetic. And since knowledge is based on intelligence (you'll learn less if you have less capability to learn), that also isn't determined by old age.
